In the face of horrific living conditions, starvation and the threat of deportation to Auschwitz, the Jewish inmates of Terezin concentration camp - artists, musicians, poets and writers - fought back ... with art and music. Led by conductor Raphael Schachter, they re-imagined a Catholic liturgical work, Verdi's Requiem, as a condemnation of the Nazis. Ultimately, they performed for Nazi brass, singing what they dared not say. Six decades later, conductor Murry Sidlin and a new choir take Verdi's Requiem back to Terezin and bring the story of Raphael Schachter's artistic uprising back to life.
